I am actually currently working on a project with .MTS footage. It plays in VLC player and I had no trouble loading it straight into Premiere Pro CC. The only issue I had with importing was that Premiere combined some of my clips. For example, say I loaded 5 .MTS files into premiere named 01, 02, 03, 04, and 05. If 01 through 04 were each 15 min long and 05 was 5 min long, Premiere would still load 5 files with the same names, but 01 though 04 would be identical 1 hour clips and 05 would still be 5 min. My project is using footage from a Canon Vixia camcorder, so that could have had something to do with it, but I thought it was worth giving a heads up.
